In particular, in marine species of unicellular cyanobacteria, various ecological variants called "ecotypes" are recognized.
In the 1930s, phenotypes unique to animal strains of S. aureus were first observed and subsequently used to define specific ecological variants (ecovars) associated with different host species (Madison 1935; Minnett 1936; Devriese 1984).
3. The model is strictly speaking ecological as all variants are assumed to be present at t 0. My understanding is that cancer progresses through mutational events and these are not treated in this model.
This variation can, furthermore, be explored at different levels of biological organization, ranging from the genetic pathways involved in trait formation [ 10] to the ecological relevance of pattern variants [ 78- 80].
Thus, this study provides a foundation for the design and insightful use of molecular markers for genetic variants whose ecological performance and fitness can be characterized in the field (e.g. [ 65]).
Therefore, we selected P. lipolytica as a model to investigate the potential ecological significance of the variants produced during biofilm formation and to explore the genetic changes that lead to the alterations of colony morphology by whole-genome re-sequencing.
Little research concentrates on the effect of different dimensions of face on consumer behavior, let alone variant effects on ecological product consumption.
The distribution of private conservation areas was compared to statutory conservation areas using several landscape characteristics: biome and vegetation variant, elevation class, ecological process area, total area, and threat status (endangerment).
Ecological barriers might result in variant divergence time between two insular groups (Taiwan and Hainan) from China mainland.
Many students reason that if natural selection acts on variability within a species, and that some of that variability is "better" than other variants for the ecological context, then such variability must exist in humans.
